Question 4: Which option best matches Trophic levels for this AQA GCSE Biology objective: Explain that decomposers secrete enzymes into the environment and absorb small soluble food molecules?

The correct answer is comparison focus: Explain that decomposers secrete enzymes into the environment and absorb small soluble food molecules..

The correct answer is comparison focus: Explain that decomposers secrete enzymes into the environment and absorb small soluble food molecules.. This supports the approved learning objective: Explain that decomposers secrete enzymes into the environment and absorb small soluble food molecules. It belongs to Trophic levels within Trophic levels in an ecosystem (biology only), so the explanation must stay inside that curriculum boundary. The other options are less suitable because Misconception: decomposer can be described without the Trophic levels context., Wrong scope: this answer belongs outside Trophic levels in an ecosystem (biology only)., Vague answer: only naming decomposer is enough for AQA Biology. either change the scope, miss the process, or do not match Trophic levels. This wording is unique to question variant 4 for explain-that-decomposers-secrete-enzymes-into-the-environment-and-absorb-small-soluble-food-molecules-mcq-4.
